Abstract (en)
[origin: WO2011029461A1] The invention relates to a method, by means of which time synchronization within an automation device is possible with relatively little effort, wherein a base timing cycle produced on a selected assembly (11a) is transmitted to at least one further assembly (11b) and is used to synchronize an assembly timing cycle of the assemblies (11a, 11b). The pulses of the base timing cycle are fed to a first counter (13a) of each of the assemblies (11a, 11b) and cause an incremental reduction of the counter reading there. The pulses of the base timing cycle are also fed to a second counter (14a, 14b) of each of the assemblies (11a, 11b) and cause an incremental increase of the counter reading there. When a counter reading of the respective first counter (13a, 13b) having the value zero is reached, a time pulse is generated, from which the respective assembly timing cycle is produced. A correction value is determined by comparing the counter readings of the two counters to the respective time pulses. The correction value is used to synchronize the first counters (13a, 13b) of the assemblies (11a, 11b). The invention further relates to a corresponding automation device (10).
